did you guys fucking know this.
holy shit.
okay, here it is

apparently .49999999999999999999...=1/2 (there is no end to the 9's, just more 9's)

what the fuck guys.

Holy shit, did you know that this has been posted at least several trillion times already? Ofcourse you do, you're a boring troll.

>> No.2529556

did you guys fucking know this.
holy shit.
okay, here it is

apparently 1/2 + 1/4 + 1/8 + 1/16 + ... = 1 (there is no end to the plusses, just more plusses)

what the fuck guys.

guy's whats going on their cant be infinity plusses done.

whats 1+1+1+1+1+1+... with no end to the plusses?

I don't know, but I'm pretty sure it's less than one million!

0.4999... doesn't equal 1/2.

Two times 0.4999... ends in an 8, which is not equal to 0.999... which is equal to 1.

I've always wondered if it's possible to formalize this line of reasoning...

>> No.2529613

can't multiply an irrational number without truncating it.

Sorry, I meant 0.499... + 0.499...

>> No.2529632

>>2529619

Can't ad them together either without making them squares and roots, where would you start?

>> No.2529635

>>2529585
Actually, since 0.49999... doesn't end at all, two times 0.499999... doesn't end either.

no it doesn't equal 1/2 it's equivalent to 1/2.

>> No.2529659

>>2529613
Wait a minute, how is 0.4999... irrational?

If you're arguing that it is the equivalent of 1/2, no fair asserting I can't multiply it by two. For you to assert that, you must first agree that it is not equal to 1/2.

>> No.2529666

>>2529644
I don't know if that was a typo but you actually typed 1/2 twice there.

>> No.2529692

>>2529659

.4999... is irrational, 1/2 is not.

>> No.2529704

The trolling continues

>> No.2529709

>>2529659
it's irrational because it does not terminate

you know the little wavy equals sign, the one made of two ~ of those

that's what you write between .499... and 1/2

>> No.2529710

>>2529692
So we agree they aren't the same. I'm satisfied.

Trolling aside, does this mean that numbers are not evenly distributed? Or does it mean that numbers we can express are not evenly distributed? Or neither of these things?

>> No.2529762

>>2529751
What do you mean, evenly distributed? There is exactly one number for each number, I'd say that's pretty evenly distributed.

>> No.2529812

>>2529762
I mean do intervals (between two numbers) of equal length always contain the same quantity of numbers?

>> No.2529821

>>2529812
Any interval has the same cardinality as the entire set of reals.

What the fuck is going on this thread? Every single post is full of shit, retardedness and trolls. What the fuck is wrong with you guys?
